SAFETY INSTRUCTIONS
3. Cutting
attachment guard
This guard is intended to
prevent objects from being
thrown towards the operator
and to protect the operator
from unintentionel contact
with the cutting attachment.
WARNING!
Under no circumstances may the cutting
!
equipment be used without an approved
guard fitted. See the chapter
data”
. If the wrong guard or a defective
guard is fitted this can cause serious
personal injury.
4. Vibration
damping system
Your machine is equipped
with a vibration damping
system, which is designed to
give as vibration-free and
comfortable use as possible.
Use of incorrectly wound
cord or incorrect cutting
equipment increases the level
of vibration.
The machine’s vibration
damping system reduces the
transfer of vibrations between
the engine unit/cutting
equipment and the machine’s
handle unit.
“Technical
!
WARNING!
Over exposure to vibrations can result in
blood-vessel or nerve injury to persons
suffering with blood circulation problems.
Seek medical attention if you experience
physical symptoms that can be related to
over exposure to vibrations. Examples of
such symptoms are “numbness“, lack of
feeling, “tickling“, “pricking“, “pain“ lack of
or a reduction in normal strength, changes
in the colour of the skin or its surfaces.
These symptoms normally appear in the
fingers, hands or wrists.

SAFETY INSTRUCTIONS
5. Muffler
The muffler is designed to
give the lowest possible noise
level and to direct the engine‘s
exhaust fumes away from the
operator. Muffler fitted with
catalytic converter is also
designed to reduce harmful
exhaust components.
In countries that have a warm
and dry climate the risk of fire
is obvious. We have therefore
fitted certain mufflers with a
spark arrest screen. Make sure
that your muffler is fitted with
this kind of screen.
It is extremely important that
the instructions for checking,
maintaining and servicing the
muffler are followed. (see the
section “Control, maintenance
and service of the machine‘s
safety equipment“).
WARNING!
!
Mufflers fitted with catalytic converters
become extremely hot during use and
after stopping. This also applies at idling
speeds. Contact can result in burns to
the skin. Be observant to the risk of fire!
6. Cutting
equipment
1) Grass blades are
intended for brush cutting.
2) The trimmer head is
intended for trimming
grass.
7. Locking nut

SAFETY INSTRUCTIONS
Cutting equipment
IMPORTANT INFORMATION
The section describes how through correct
maintenance and through using the right type of
cutting equipment you can reduce the machine‘s
tendency to kickback, obtain maximum clearing
capacity and increase the service life of the cutting
equipment.
• Only use the cutting and guard equipment we
recommend! See chapter
•
Refer to the instructions for the cutting equipment
for the correct winding of cord and for the
selection of the right cord diameter.
• Keep the blade’s teeth well and correctly
sharpened! Follow our recommendations. Also
refer to the instructions on the blade packaging.
WARNING!
Incorrect cutting equipment or an
!
incorrectly sharpened blade increases
the risk of kickback.
Filing the grass
blade
• See the cutting equipment’s
packaging for correct filing
instructions.
“Technical data“.
• Generally smaller machines require a small trimmer head
and vice versa. This is because when clearing using a cord
the engine must throw out the cord radially from the
trimmer head and also meet resistance from the grass being
cleared.
• The length of the cord is also important. A longer cord
requires greater engine power than a shorter cord of the
same diameter.
• Make sure the knife positioned on the trimmer guard is
intact. This is used to cut the cord to the correct length.
• To increase the life of the cord it can be soaked in water for
a few days. This will make the line tougher and it will keep
longer.
IMPORTANT INFORMATION
Always ensure the trimmer cord is wound tightly
and evenly around the drum, otherwise harmful
vibrations will occur.
WARNING!
!
Always stop the engine before starting
work on any part of the cutting equipment.
This continues to rotate even after the
throttle has been released. Ensure that the
cutting equipment has stopped completely
and remove the cable from the spark plug
before you start to work on it.
• The blades are sharpened
using a single cut flat file.
• Sharpen all edges equally to
maintain the balance of the
blade.
Trimmer head
• Only use a trimmer head
and trimmer cord that is
recommended. These have
been tested by the
manufacturer to suit a
particular engine size. This
is especially important
when a fully automatic
trimmer head is used. Only
use the cutting equipment
we recommend! See chapter
“Technical data“.

SAFETY INSTRUCTIONS
General working instructions
IMPORTANT INFORMATION
• This section takes up the basic safety
precautions for working with the trimmer.
• If you encounter a situation where you are
uncertain how to proceed you should ask an
expert. Contact your dealer or your service
workshop.
• Avoid all usage which you consider to be
beyond your capability.
Basic safety precautions
1.Observe your surroundings:
• To ensure that people, animals or other things cannot affect
your control of the machine.
• To ensure that the above mentioned do not come into
contact with the cutting equipment or objects that can be
thrown by the cutting equipment.
• NOTE! Never use a machine without the possibility of
calling for help in the event of an accident.
Basic working techniques
• Always drop to idling speed after each working operation.
Longer periods running at full throttle without loading the
engine (that is without resistance, which the engine feels
from the cutting equipment when trimming) can lead to
serious engine damage.
Designations
• Brush cutting is a general
term for clearing grass.
Grass blades are used for
this purpose.
• Grass trimming is a
general term for light
clearing, e.g. around edges
or around trees. A
trimmer head or plastic
blade is used.
WARNING!
Sometimes branches, grass or wood can
!
get caught between the guard and cutting
equipment. Always stop the engine when
cleaning.
2.Avoid usage in
unfavourable weather
conditions. For example,
thick fog, heavy rain,
strong winds or extreme
cold, etc. To work in bad
weather conditions is tiring
and can create dangerous
circumstances, e.g. slippery
surfaces.
3.Make sure you can walk
and stand safely. Look out
for any obstacles with
unexpected movement
(roots, stones, branches,
pits, ditches, etc.). Take
great care when working
on sloping ground.
4.The engine should be switched off before moving. When
moving over longer distances and transporting the transport
guard should be used.
5.Never put the machine down with the engine running
unless you have good sight of it.
Brush cutting using a grass blade
• A blade is used for all
types of high or thick
grass.
• The grass is cut down
with a sideways, swinging
movement, where the
movement from right-toleft is the clearing stroke
and the movement from
left-to-right is the return
stroke. Let the blade work
on the left-hand side
(between 8 and 12
o’clock).
• If the blade is angled to the left when clearing the grass will
collect in a line, which makes collection easier, e.g. when
raking.
• Try to work rhythmically. Stand firmly with your feet apart.
Move forward after the return stroke and stand firmly again.
• Let the support cup rest lightly against the ground. It is used
to protect the blade from hitting the ground.
• Reduce the risk of material wrapping around the blade by
following these instructions:
a) Always work at full throttle.
b) Avoid the previously cut material during the return
stroke.
• Stop the engine, loosen the harness and place the machine
on the ground before you start to collect the cut material.

SAFETY INSTRUCTIONS
Grass trimming
using the trimmer
head and plastic
knifes
• Hold the trimmer head
just above the ground at an
angle. It is the end of the
cord that carries out the
work. Let the cord work at
its own pace. Do not press
the cord into the area to be
cut.
• The cord can easily remove
grass and weeds up against
walls, fences, trees and
borders, however, it can
also damage sensitive bark
on trees and bushes and
damage fence posts.
• Reduce the risk of
damaging plants by
shortening the cord to 1012 cm and reducing the
engine speed.
Clearing
• The clearing technique
removes all unwanted
vegetation. Keep the
trimmer head just above
the ground and tilt it. Let
the end of the cord strike
the ground around trees,
posts, statues and the like.
NOTE! This technique
increases the wear on the
cord.
• The cord wears quicker
and must be fed forward
more often when working
against stones, brick,
concrete, metal fences, etc.
than when coming into
contact with trees and
wooden fences.
• When trimming and
clearing you should use less
than full throttle so that
the cord lasts longer and to
reduce the wear on the
trimmer head.
Trimming
• The trimmer is ideal to cut
grass that is difficult to
reach using a normal lawn
mower. Keep the cord
parallel to the ground
when cutting. Avoid
pressing the trimmer head
against the ground as this
can ruin the lawn and
damage the tool.
• Do not allow the trimmer
head to constantly come
into contact with the
ground during normal
cutting procedures.
Constant contact can cause
damage and wear to the
trimmer head.
Sweeping
• The rotating cord‘s
fanning effect can be used
for quick and easy
cleaning. Hold the cord
parallel to and above the
area to be swept and move
the trimmer from side to
side.
• When cutting and
sweeping you should use
full throttle to obtain the
best results.
WARNING!
Neither the user of the tool or anyone else
!
!
may attempt to remove the cut material while
the engine is running or with the blade
rotating as this can result in serious injury.
Stop the engine and blade before you
remove material that has wound around the
blade as otherwise there is a risk of injury.
The bevel gear unit can get hot during use
and may remain so for a while afterwards.
There is a risk of slight burns if you touch it.
WARNING!
Warning for thrown objects. Always wear
protective glasses. Never lean over the
guard. Stones, rubbish, etc. can be thrown
up into the eyes causing blindness or
serious injury.
Keep unauthorised persons at a distance.
Children, animals, onlookers and helpers
should be kept outside the safety zone of
15 m (50 feet). Stop the machine
immediately if anyone approaches.
